Title: Semiconductor device
Inventor: TAKAGI YOSHIYUKI
IPC: H01L21/027
Filed: 1983-12-20
Abstract: PURPOSE:To improve the integration of the semiconductor device by performing mask alignment with using at least one of electrode pads also as an aligning mark so as to eliminate the aligning-mark occupying area. CONSTITUTION:On the semiconductor substrate, electrode leading-out pads 42- 45, circuits 44 and aligning marks 45-47 are formed and the mark 45 is also used as a pad. When the minimum measurement of accuracy for mask alignment is 2mum, the biggest aligning mark is made to be accordant with the pad size, the middle one is minimized each side by 2mum and the smallest one has to be further minimized each side by more 2mum. A positive mark smaller only by the minimum measurement accuracy compare with the mark formed in the last process or a negative mark bigger only by the minimum measurement accuracy compared with that is fitted. Thus, the mark necessary for mask alignment of photolithography mask can be also used as a pad for wire-bonding with external electrodes of a semiconductor device (for electrode leading-out). Accordingly, an occupied area by the marks is substantially reduced as a whole so as to improve the integration.

Abstract: PURPOSE:To accurately and easily adjust an exposure position by arranging respective sensors almost on a scanning line on a photosensitive material and detecting direct irradiation light. CONSTITUTION:The light of a semiconductor laser LD1 for red is regarded as reference light, and then the time required to scan this reference light between a line synchronism detecting means 260 and an irradiation light detecting means 270 is measured. Then when it is considered that the reference light is scanned nearby the line synchronism detecting means 260, the reference light is emitted and detected; and the time from the point of time to the detection of some other light by the irradiation light detecting means 270 is measured and the irradiation position is found from the difference between those two measured values. Other light beams are processed similarly to detect deviations from the reference light, and those are used to perform light emission timing control. Consequently, the exposure position is easily and accurately adjusted.

Abstract: PURPOSE:To attain the high speed in making a tunnel chip and a recording layer close together by providing a recording medium with a space adjusting protrusion which is slidable on a substrate having plural probes and by which a space to the substrate is adjusted. CONSTITUTION:Spacing adjustment is performed until being in contact with multiprobes and the space adjusting protrusion 6 that is provided in a part of a storage medium. Concurrently with the contact, the movement of a coarse adjusting mechanism 204 is immediately stopped, and its position is retained.

Title: Speed change shock reducing device for automatic transmission
Inventor: TAKEDA HITOSHI
IPC: F16H59/40
Filed: 1985-10-29
Abstract: PURPOSE:To enable execution of processing by means of a digital circuit delayed in computation processing, by a method wherein a feed pressure on a friction element is controlled by three variation characteristics in response to the starting of fastening of the friction element detected during a change in output shaft torque and at each point of time when a minimum or a maximum point is produced. CONSTITUTION:Where an operating condition needs speed change, a change in the reference pressure of a feed fluid pressure is determined during a time ending with a fastening starting point of time tS of a friction element. Right after the starting of speed change, a pressure data PF is outputted as a pressure instruction value P to a circuit 31 to feed a fluid pressure to the friction element, and the fluid pressure is controlled according to first change characteristics. When a fastening starting point of time tS is detected, the data PF is varied into data decided by second change characteristics, and the changed data is divided into data in plural cases according to a kind of speed change and an operating condition to reduce pressure data. After a point of time tB lapses when a minimum point is produced, data is varied into decision data of third change characteristics to gradually increase a feed pressure. After transmission motion is completed, a difference in torque between a minimum point tB and a maximum point tF forms a fluctuation width DELTATOUT to decide the quality of speed change motion.
